Paging with OData and Excel

I'm using OData to send data to Excel. My Get-Function in my control:
Public Function Get As EdmEntityObjectCollection

I create a dynamic edm and all is ok, when I have only less data. Without top xxxx , I get an timeout.
How can I set the controller to transfer allways only perhaps 100 rows and with the next request, the next 100?
The top in queryOptions is at the moment allways empty.
